DUMPlNG-WAGON.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed December 28, 1906. Serial No. 349,891.

To all whom it may concern:

Be it known that I, JAooB S. BLAOKWOOD, a citizen of the United States,residing at C0- lumbus, in the county of Bartholomew and State ofIndiana, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

This invention relates to wagons embodying bodies for receiving a load,and which bodies are of sectional formation and mounted to admit of thesections separating to effect discharge of the load when it is requiredto dump the same. i

The present invention has for its object to improve the generalstructure of wagons of the type aforesaid, whereby their usefulness isenhanced and the operation of opening and closing the sections of thebody greatly simplified. 1

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction and the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, in which Figure 1 is a perspectiveview of a dumping-wagon embodying the invention. Fig. 2 is a centrallongitudinal section of the wagon. Fig. 3 is an end view of the body,showing the side bars of the truck or running-gear in section andillustrating the relation of the parts when said body is closed. Fig. 4is a transverse section of the wagon, showing the relation of the partswhen thesections of the body are separated to dump the load.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The body is composed of two similar sec tions 1, which are pivotallymounted to swing outward when it is required to dump the load, thesections being pivotally connected at 2 to each other and to supports 3,the latter rising from the framework of the truck or running-gear. Thesections 1 of the body are referably formed of sheet metal, the lat-.

ter eing suitably strengthened by anglebars 4, riveted or otherwiseattached to the outer sides of the sections and extending lengthwisethereof. In the end view each section 1 is of sector shape, beingapproximately oneuarter of a circle, the outer side and bottom beingformed on a circle having its center corresponding with a straight lineconnecting the pivot-supports 2. To hold the sections when closed, acatch 5 is provided at each end of the body and is pivoted to one of thesections and adapted to engage over projecting portions of the oppositesection and which projecting portions constitute end extensions of theangle-bar 4, secured to the lower edge of the section. The

catches 5 are connected, by means of a cord 6, which after passing oversuitably-arranged guide-pulleys 7 extends within convenient reach of thedrivers seat to admit of release of the catches when it is required toeffect dischar e of the load.

The i 'ramework of the truck or runninggear comprises side bars 8 andend pieces 9, the latter forming platforms, as well as serving toconnect the side bars 8 at their ends. The supporting-wheels are appliedto axles, which in turn are fitted to the framework in any accustomedway. The space between the side bars 8 and end cross-pieces 9 is such asto receive the body. Rollers 10 are located near opposite ends of theside bars and assist materially in supporting the body and relieve thepivot-fastening 2 of the carrier part of the strain and load. By havingthe pulleys 10 arranged adjacent to the end pieces 9 the weight of theload is transferred thereto through the end pieces of the sections ldthereby preventing inward bending of the s1 es.

The posts 3 or uprights are secured at their lower ends to the endpieces 9 or bolsters and are strengthened by lateral braces 11. stoutrod 12 is mounted in the upper ends of the posts 3 and is provided atone end with a crank 13.

Chains or cables 14 connect end portions of the rod 12 with oppositecorners of the body-sections 1. Upon turning the shaft 12 afterreleasing the catches 5 the chains or cables 14 are wound thereon andefiect a separation of the sections 1, thereby permitting discharge ofthe load.

A crane 15 is located at one end of the wagon, and the post is slippedat its lower end in the end piece and is hingedly connected near itsupper end to the proximal upright or post. The boom or horizontal beam16 of -nected by means of a brace 17 to the lower .venient way, eitherby means of the crane and the crane is extended at one end and isconbucket 20 or by pitching material into the body in any way commonlypracticed forloading wagons of the type disclosed. When it is requiredto dump the load, the catches 5 are released and the rod 12 rotated bymeans of the crank-handle 15 to wind the chains or cables 14 thereon anddraw the sections 1 apart, so as to permit automatic discharge of theload.

Havin thus described the invention, what is claimed as new is a 1. In adumping-wagon, the combination of a framework, comprising side bars andI end pieces, uprights projected upward from a said end pieces, awagon-body comprising similar sector-shaped sections, means pivotallyconnecting said sections to each other at their upper inner corners andto the re spective uprights, rollers applied to the sidebars of theframework adjacent to the end pieces to make contact with the sectionsof the body opposite the end pieces of the said body-sections, means forsecuring the sections of the body when closed, and means for openingsaid sections to eifect discharge of the load.

2. In a dumping-wagon, the combination of a framework comprising sidebars and end pieces, a body comprising similar sections pivotallyconnected and adapted to swing outward and upward, uprights at the endsof the framework, a rod journaled to said uprights and flexibleconnections between said rod and the sections of the body and adapted toeffect an opening of the latter upon rotation of the said rod.

3. In a dumping-wagon, the combination of a framework, a body comprisingsections adapted to open outward, bars applied to the sides of saidsections for stiffening and strengthening the same and catchescooperating with certain bars to hold the sections when closed.

In testimony whereof I affix in presence of two witnesses.

JACOB S. BLAOKWOOD.
